IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 178,976, dated J une '20, 1876; application filed I F April 18, 1876.

To all whom it may concern Be it known that I, JAMES HENRY SWIFT, of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and Improved Door-Fastening, of which the following is a specification: I t

The invention consists in the improvement of door-checks by attaching to door-frame a curved or are bar having a series of bolt-holes, and so arranged as to pass through a slot of the bolt-case, as herein-after more fully described and definitely claimed.

Figural is a side elevation of a door with my improved fastener. Fig. 2 is a horizontal section on line w m. Fig. 3 is a vertical section.

A is the curved bar, fastened to the facing of the doorframe above the door, and having a series of bolt-holes, B; G is the spring-bolt, arranged vertically in a case, D, attached to the door, and connected, by bell-cranks E F and Wires G H, to the knob I, so that by turning the knob the bolt will be pulled out of the bar, to allow the door to swing. The spring J throws the bolt back into the holes of the bar to lock the door. on both sides, at K, to connect the bell-crank E, for right or left hand doors. P is a cushion to prevent the door from swinging too far back. A

The apparatus being located at the top of the door, it is entirely out of the way, and it avoids the use of the objectionable Z-stops sometimes usedon the floor or the base-board.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- V In door-checks, the curved or are bar A, attached to door-frame, having a series of boltholes, B, at intervals, and passing through a slot, K, of bolt-case D, as shown and described. v
